“…Wastewaters from textile industry are considered as one of the major sources of pollution due to the great demand for textile products resulting proportional increase in production and application of synthetic dyes (Balapure et al, 2014). Azo dyes represent the most common group of synthetic dyes constituting 60-70% of more than 10,000 dyes used in textile industry (Ong et al, 2010).…”

“…The river bed of Noyyal across Tirupur may be a source of microbes having potential to degrade pollution load of textile effluent (Arunprasad and Bhaskara Rao 2010). Surface water quality is highly deteriorated by the direct release of textile effluents (Balapure et al 2015). Due to high xenobiotic load of chemicals into the environment, i.e., habitat of microbes, some microorganisms and microbial communities have developed the ability to process them.…”

The expedited advent of urbanization and industrialization for economic growth has adversely affected the biological diversity, which is one of the major concerns of the developing countries. Microbes play a crucial role in decontaminating polluted sites and degrades pollution load of textile effluent. The present study was based on identification of microbial diversity along the Noyaal river of Tirupur area. River water samples from industrial and non-industrial sites and effluent samples of before and after treatment were tested and it was found that microbial diversity was higher in the river water at the industrial site (Kasipalayam) as compared to the non-industrial site (Perur). Similarly, the microbial populations were found to be high in the untreated effluent as compared to the treated one by conventional treatment systems. Similar trends were observed for MBR treatment systems as well. Pseudomonas sp., Achromobacter sp. (bacterial species) and Aspergillus fumigates (fungal species), found exclusively at the industrial site have been reported to possess decolorization potential of dye effluent, thus can be used for treatment of dye effluent. The comparison of different microbial communities from different dye wastewater sources and textile effluents was done, which showed that the microbes degrade dyestuffs, reduce toxicity of wastewaters, etc. From the study, it can be concluded that the microbial community helps to check on the pollutants and minimize their affect. Therefore, there is a need to understand the systematic variation in microbial diversity with the accumulation of pollution load through monitoring.

“…Out of more than 900,000 metric tons of dyes produced annually [12], more than 70% belongs to the azo group [11,13]. Many dyes used in textile are only known by their trade name and not their actual chemistry that is the main reason behind causing acute toxic effect where no possible solution to dye degradation can be taken.…”

By releasing of azo dye through textile effluent, textile industry is the main cause of water pollution resulting into acute effect on environment and human health. Development of any eco-friendly and cost-effective method that may address the drawbacks to physical or chemical methods of dye removal is the recent global priority. Physical or chemical methods for textile wastewater pretreatment are of high cost, extremely energy consuming, and environmentally low efficient and generate toxic sludge. Thus, the use of microbial technique for textile dye degradation will be eco-friendly and is probably a lucrative alternative to physico-chemical processes. Microbial enzymes, viz. laccase and azoreductase, are cost-efficient, easy to harvest, easily downstream processable, and effortlessly mobilizable. Recent research trends on nanoparticle-microbial enzyme conjugates are also highly efficient to remove the azo dye from textile waste within a few minutes. But unfortunately, due to some gap between academia and industry, these methods remain only limited up to laboratory and its industrialization is still a challenge. The present review is an illustrated compilation of the use of microbial enzymes in removal of textile dyes.
